Hinged Electronic Device with Moving Support Plates for a Flexible Display and Corresponding Systems

ABSTRACT

An electronic device includes a first device housing and a second device housing. Each can optionally define a linear recess. A hinge couples the first device housing to the second device housing. The first device housing is pivotable about the hinge relative to the second device housing. A flexible display is situated in the linear recess, where included, and spans the hinge. The hinge includes a cam, a first support plate pivotally coupled to a first side of the cam, and a second support plate pivotally coupled to a second side of the cam. The first support plate, the cam, and the second support plate bridge the linear recess of each device housing when the electronic device is in an axially displaced open position, but define boundaries within which the flexible display defines a service loop when the electronic device is in a closed position.

CROSS REFERENCE TO PRIOR APPLICATIONS

This application is a continuation application claiming priority andbenefit under 35 U.S.C. § 120 from U.S. application Ser. No. 16/131,937,filed Sep. 14, 2018, which is incorporated by reference for allpurposes.

BACKGROUND Technical Field

This disclosure relates generally to electronic devices, and moreparticularly to hinged electronic devices.

Background Art

Portable electronic communication devices, especially smartphones, havebecome ubiquitous. People all over the world use such devices to stayconnected. People use these devices for many different purposesincluding, but not limited to, voice communications and datacommunications for text messaging, Internet browsing, commerce such asbanking, and social networking.

Mobile devices have been designed in various mechanical configurations.A first configuration, known as a “candy bar,” is generally rectangularin shape, has a rigid form factor, and has a display disposed along amajor face of the electronic device. By contrast, a “clamshell” devicehas a mechanical hinge that allows one housing to pivot relative to theother.

Some consumers prefer candy bar devices, while others prefer clamshelldevices. Users may prefer the latter for a variety of reasons. Clamshelldevices, when folded, generally have a smaller form factor than do candybar devices. They therefore fit more easily in a pocket. Next, clamshelldevices provide protection from the display when folded. This is incontrast to candy bar devices where the display is always exposed. Itwould thus be desirable to have an improved hinged electronic device.

DETAILED DESCRIPTION OF THE DRAWINGS

Embodiments of the disclosure are now described in detail. Referring tothe drawings, like numbers indicate like parts throughout the views. Asused in the description herein and throughout the claims, the followingterms take the meanings explicitly associated herein, unless the contextclearly dictates otherwise: the meaning of “a,” “an,” and “the” includesplural reference, the meaning of “in” includes “in” and “on.” Relationalterms such as first and second, top and bottom, and the like may be usedsolely to distinguish one entity or action from another entity or actionwithout necessarily requiring or implying any actual such relationshipor order between such entities or actions. As used herein, componentsmay be “operatively coupled” when information can be sent between suchcomponents, even though there may be one or more intermediate orintervening components between, or along the connection path. The terms“substantially” and “about” are used to refer to dimensions,orientations, or alignments inclusive of manufacturing tolerances. Thus,a “substantially orthogonal” angle with a manufacturing tolerance ofplus or minus two degrees would include all angles between 88 and 92,inclusive. Also, reference designators shown herein in parenthesisindicate components shown in a figure other than the one in discussion.For example, talking about a device (10) while discussing figure A wouldrefer to an element, 10, shown in figure other than figure A.

Embodiments of the disclosure provide an electronic device that includesat least a first device housing and a second device housing. In one ormore embodiments, a hinge couples the first device housing to the seconddevice housing so that the first device housing is pivotable about thehinge relative to the second device housing to one or more of a bentconfiguration, a folded configuration, or other configuration. In one ormore embodiments, a flexible display is coupled to the first devicehousing and the second device housing and spans the hinge. The flexibledisplay deforms when the first device housing pivots about the hingerelative to the second device housing.

In one or more embodiments, the hinge not only facilitates the bendingoperation, but also works to improve the reliability and usability ofthe flexible display. In one or more embodiments, the hinge does thisvia the use of one or more support plates that are coupled to the camand are pivotable about the cam when the first device housing pivotsabout the hinge relative to the second device housing.

In one or more embodiments, a first support plate is pivotally coupledto a first side of the cam. The first support plate then extendsdistally into the first device housing from the first side of the cam.Similarly, a second support plate is pivotally coupled to a second sideof the cam. The second support plate extends distally into the seconddevice housing from the second side of the cam.

The cam and its corresponding support plates serve two functions. First,they provide mechanical support for the flexible display when the firstdevice housing has pivoted about the hinge relative to the second devicehousing to an axially displaced open position. However, when the firstdevice housing pivots about the hinge relative to the second devicehousing to a closed position in which interior surfaces of the firstdevice housing and the second device housing abut, the support platestranslate along inclined planes within the first device housing andsecond device housing, respectively, to recede into the first devicehousing and second device housing. Said differently, when the firstdevice housing pivots about the hinge relative to the second devicehousing to the closed position, the support plates move toward theexterior surfaces of the first device housing and the second devicehousing, thereby receding “outward” from the interior surfaces of thefirst device housing and the second device housing. This “collapse” ofthe first support plate and the second support plate creates a cavity inthe hinge portion of the electronic device that allows the flexibledisplay to form a service loop when the electronic device is in theclosed position. The service loop prevents the flexible display frombeing damaged or developing memory in the folded position when theelectronic device is in the closed position.

Embodiments of the disclosure contemplate that bending operationsoccurring in a housing of an electronic device with a flexible displaycan present technical challenges. Illustrating by example, it can bedifficult to provide uniform mechanical support beneath the flexibledisplay when the electronic device is in the open position. It canfurther be difficult to limit deformation due to bending operations suchthat the deformation occurs within a predefined radius.

Advantageously, embodiments of the disclosure provide solutions to eachone of these challenges. Specifically hinges configured in accordancewith one or more embodiments of the disclosure provide a solution thatprovides the needed system flexibility by providing support for theflexible display when in the open position, but allows for a largeradius service loop of the flexible display to occur when the electronicdevice is in the closed position.

In one or more embodiments, each of the first device housing and thesecond device housing defines a support plate receiving recess at thehinged portion of the electronic device. In one or more embodiments,these support plate receiving recesses each comprise an inclined plane,which is physically separated from the cam of the hinge by a predefineddistance. A distal end of each support plate contacts the inclined planeto translate along the inclined plane when the first device housingpivots about the hinge relative to the second device housing. Thus, if afirst side of a first support plate is coupled to the cam, a second,distal side of the first support plate contacts the inclined plane inthe support plate receiving recess of the first device housing. Thesecond, distal side of the first support plate then translates along theinclined plane when the first device housing pivots about the hingerelative to the second device housing. A second support plate andsupport plate receiving recess can be similarly configured in the seconddevice housing.

The distal ends of each of the first support plate and the secondsupport plate therefore travel, in one or more embodiments, along theirrespective inclined planes between a first position within the firstdevice housing and the second device housing, respectively, to a secondposition within the first device housing and the second device housing,respectively, when the first device housing and the second devicehousing pivot about the hinge from an axially displaced open position toa closed position. In one or more embodiments, the support plates arecloser to the flexible display when in the first position, and arefarther from the flexible display when in the second position. In one ormore embodiments, the support plates are farther from exterior surfacesof the first device housing and the second device housing when in thefirst position, but are closer to those outer surfaces of the firstdevice housing and the second device housing when in the secondposition. This results in the second position being deeper within thefirst device housing and the second device housing, respectively, thanthe first position.

In one or more embodiments, the flexible display is positioned within alinear recess of the first device housing and the second device housingso that it—or a fascia disposed atop the flexible display—can be flushwith the interior surfaces of the first device housing and second devicehousing, respectively. In other embodiments, the linear recess will beomitted and the flexible display will simply sit atop planar interiorsurfaces of the first device housing and the second device housing. Ineither embodiment, when the first device housing pivots about the hingerelative to the second device housing to the axially displaced, openposition, the first support plate, the cam, and the second support platebridge the linear recess (or planar interior surfaces) to providemechanical support for the flexible display. By contrast, by recedinginto the housings, the first support plate, the cam, and the secondsupport plate define boundaries within which the flexible displaydefines a service loop when the first device housing and the seconddevice housing pivot about the hinge from the axially displaced openposition to a closed position.

Embodiments of the disclosure thus provide a novel hinge mechanism thatproperly supports a flexible display when a hinged electronic device isin the open position. Embodiments of the disclosure contemplate that themechanical stack of the flexible display is frequently too soft orflexible to support itself. Accordingly, when the electronic device isin the open position the support plates provide rigid support across thehinge portion of the electronic device. At the same time, the supportplates receded into the housing when the electronic device is folded toallow the flexible display to form a service loop. Advantageously, thecam and corresponding support plates define kinematic linkages that movewhen the first device housing pivots about the hinge relative to thesecond device housing to the closed position. As noted above, thesupport plates recede backwards (along the Z-axis) to provide space forthe flexible display to bend into a teardrop shaped service loop. In oneor more embodiments, one or both of the first device housing or thesecond device housing can also include a spring loaded support platethat stretches the flexible display when the electronic device is in theopen position.

Turning now to FIG. 1, illustrated therein is one explanatory electronicdevice 100 configured in accordance with one or more embodiments of thedisclosure. The electronic device 100 of FIG. 1 is a portable electronicdevice. For illustrative purposes, the electronic device 100 is shown asa smartphone. However, the electronic device 100 could be any number ofother devices as well, including tablet computers, gaming devices,multimedia players, and so forth. Still other types of electronicdevices can be configured in accordance with one or more embodiments ofthe disclosure as will be readily appreciated by those of ordinary skillin the art having the benefit of this disclosure.

The electronic device 100 includes a first device housing 102 and asecond device housing 103. In one or more embodiments, a hinge 101couples the first device housing 102 to the second device housing 103.In one or more embodiments, the first device housing 102 is selectivelypivotable about the hinge 101 relative to the second device housing 103.For example, in one or more embodiments the first device housing 102 isselectively pivotable about the hinge 101 between a closed position,shown and described below with reference to FIG. 2, and an openposition, shown and described below with reference to FIGS. 4-5.

In one or more embodiments the first device housing 102 and the seconddevice housing 103 are manufactured from a rigid material such as arigid thermoplastic, metal, or composite material, although othermaterials can be used. Still other constructs will be obvious to thoseof ordinary skill in the art having the benefit of this disclosure. Inthe illustrative embodiment of FIG. 1, the electronic device 100includes a single hinge. However, in other embodiments two or morehinges can be incorporated into the electronic device 100 to allow it tobe folded in multiple locations.

This illustrative electronic device 100 of FIG. 1 includes a display105. The display 105 can optionally be touch-sensitive. In oneembodiment where the display 105 is touch-sensitive, the display 105 canserve as a primary user interface of the electronic device 100. Userscan deliver user input to the display 105 of such an embodiment bydelivering touch input from a finger, stylus, or other objects disposedproximately with the display.

In one embodiment, the display 105 is configured as an organic lightemitting diode (OLED) display fabricated on a flexible plasticsubstrate. This allows the display 105 to be flexible so as to deformwhen the first device housing 102 pivots about the hinge 101 relative tothe second device housing 103. However, it should be noted that othertypes of displays would be obvious to those of ordinary skill in the arthaving the benefit of this disclosure.

In one or more embodiments, an OLED is constructed on flexible plasticsubstrates can allow the display 105 to become flexible in one or moreembodiments with various bending radii. For example, some embodimentsallow bending radii of between thirty and six hundred millimeters toprovide a bendable display. Other substrates allow bending radii ofaround five millimeters to provide a display that is foldable throughactive bending.

Other displays can be configured to accommodate both bends and folds. Inone or more embodiments the display 105 may be formed from multiplelayers of flexible material such as flexible sheets of polymer or othermaterials. In this illustrative embodiment, the display 105 is coupledto the first device housing 102 and the second device housing 103.Accordingly, the display 105 spans the hinge 101 in this embodiment.

In this illustrative embodiment,connector 109 is an analog connector disposed on a first end, i.e., thetop end as viewed in FIG. 1, of the electronic device 100, whileconnector 110 is a digital/power connector disposed on a second endopposite the first end, which is the bottom end as viewed in FIG. 1.

A block diagram schematic 111 of the electronic device 100 is also shownin FIG. 1. In one embodiment, the electronic device 100 includes one ormore processors 112. In one embodiment, the one or more processors 112can include an application processor and, optionally, one or moreauxiliary processors. One or both of the application processor or theauxiliary processor(s) can include one or more processors. One or bothof the application processor or the auxiliary processor(s) can be amicroprocessor, a group of processing components, one or more ASICs,programmable logic, or other type of processing device.

The application processor and the auxiliary processor(s) can be operablewith the various components of the electronic device 100. Each of theapplication processor and the auxiliary processor(s) can be configuredto process and execute executable software code to perform the variousfunctions of the electronic device 100. A storage device, such as memory113, can optionally store the executable software code used by the oneor more processors 112 during operation.

In this illustrative embodiment, the electronic device 100 also includesa communication circuit 114 that can be configured for wired or wirelesscommunication with one or more other devices or networks. The networkscan include a wide area network, a local area network, and/or personalarea network. Examples of wide area networks include GSM, CDMA, W-CDMA,CDMA-2000, iDEN, TDMA, 2.5 Generation 3GPP GSM networks, 3rd Generation3GPP WCDMA networks, 3GPP Long Term Evolution (LTE) networks, and 3GPP2CDMA communication networks, UMTS networks, E-UTRA networks, GPRSnetworks, iDEN networks, and other networks.

The communication circuit 114 may also utilize wireless technology forcommunication, such as, but are not limited to, peer-to-peer or ad hoccommunications such as HomeRF, Bluetooth and IEEE 802.11 (a, b, g or n),and other forms of wireless communication such as infrared technology.The communication circuit 114 can include wireless communicationcircuitry, one of a receiver, a transmitter, or transceiver, and one ormore antennas 115.

In one embodiment, the one or more processors 112 can be responsible forperforming the primary functions of the electronic device 100. Forexample, in one embodiment the one or more processors 112 comprise oneor more circuits operable with one or more user interface devices, whichcan include the display 105, to present, images, video, or otherpresentation information to a user. The executable software code used bythe one or more processors 112 can be configured as one or more modules116 that are operable with the one or more processors 112. Such modules116 can store instructions, control algorithms, logic steps, and soforth.

In one embodiment, the one or more processors 112 are responsible forrunning the operating system environment of the electronic device 100.The operating system environment can include a kernel and one or moredrivers, and an application service layer, and an application layer. Theoperating system environment can be configured as executable codeoperating on one or more processors or control circuits of theelectronic device 100. The application layer can be responsible forexecuting application service modules. The application service modulesmay support one or more applications or “apps.” The applications of theapplication layer can be configured as clients of the applicationservice layer to communicate with services through application programinterfaces (APIs), messages, events, or other inter-processcommunication interfaces. Where auxiliary processors are used, they canbe used to execute input/output functions, actuate user feedbackdevices, and so forth.

In one embodiment, the electronic device 100 includes one or more flexsensors 117, operable with the one or more processors 112, to detect abending operation that causes the first device housing 102 to pivotabout the hinge 101 relative to the second device housing 103, therebytransforming the electronic device 100 into a deformed geometry, such asthat shown in FIGS. 2-3. The inclusion of flex sensors 117 is optional,and in some embodiment flex sensors 117 will not be included.

In one embodiment, the flex sensors 117 comprise passive resistivedevices manufactured from a material with an impedance that changes whenthe material is bent, deformed, or flexed. By detecting changes in theimpedance as a function of resistance, the one or more processors 112can use the one or more flex sensors 117 to detect bending of the firstdevice housing 102 about the hinge 101 relative to the second devicehousing 103. In one or more embodiments, each flex sensor 117 comprisesa bi-directional flex sensor that can detect flexing or bending in twodirections. In one embodiment, the one or more flex sensors 117 have animpedance that increases in an amount that is proportional with theamount it is deformed or bent.

In one embodiment, each flex sensor 117 is manufactured from a series oflayers combined together in a stacked structure. In one embodiment, atleast one layer is conductive, and is manufactured from a metal foilsuch as copper. A resistive material provides another layer. Theselayers can be adhesively coupled together in one or more embodiments.The resistive material can be manufactured from a variety of partiallyconductive materials, including paper-based materials, plastic-basedmaterials, metallic materials, and textile-based materials. In oneembodiment, a thermoplastic such as polyethylene can be impregnated withcarbon or metal so as to be partially conductive, while at the same timebeing flexible.

In one embodiment, the resistive layer is sandwiched between twoconductive layers. Electrical current flows into one conductive layer,through the resistive layer, and out of the other conductive layer. Asthe flex sensor 117 bends, the impedance of the resistive layer changes,thereby altering the flow of current for a given voltage. The one ormore processors 112 can detect this change to determine an amount ofbending. Taps can be added along each flex sensor 117 to determine otherinformation, including the amount of bending, the direction of bending,and so forth. The flex sensor 117 can further be driven by time-varyingsignals to increase the amount of information obtained from the flexsensor 117 as well. While a multi-layered device as a flex sensor 117 isone configuration suitable for detecting at least a bending operationoccurring to deform the electronic device 100 and a geometry of theelectronic device 100 after the bending operation, others can be used aswell. Other types of flex sensors 117 will be obvious to those ofordinary skill in the art having the benefit of this disclosure.

In one embodiment, the one or more processors 112 may generate commandsor execute control operations based on information received from thevarious sensors, including the one or more flex sensors 117, the userinterface 118, or the other sensors 119. The one or more processors 112may also generate commands or execute control operations based uponinformation received from a combination of the one or more flex sensors117, the user interface 118, or the other sensors 119. Alternatively,the one or more processors 112 can generate commands or execute controloperations based upon information received from the one or more flexsensors 117 or the user interface 118 alone. Moreover, the one or moreprocessors 112 may process the received information alone or incombination with other data, such as the information stored in thememory 113.

The one or more other sensors 119 may include a microphone, an earpiecespeaker, a second loudspeaker (disposed beneath speaker port 107), and auser interface component such as a button or touch-sensitive surface.The one or more other sensors 119 may also include key selectionsensors, proximity sensors, a touch pad sensor, a touch screen sensor, acapacitive touch sensor, and one or more switches. Touch sensors mayused to indicate whether any of the user actuation targets present onthe display 105 are being actuated. Alternatively, touch sensorsdisposed in the electronic device 100 can be used to determine whetherthe electronic device 100 is being touched at side edges or major facesof the first device housing 102 or the second device housing 103. Thetouch sensors can include surface and/or housing capacitive sensors inone embodiment. The other sensors 119 can also include audio sensors andvideo sensors (such as a camera).

The other sensors 119 can also include motion detectors, such as one ormore accelerometers or gyroscopes. For example, an accelerometer may beembedded in the electronic circuitry of the electronic device 100 toshow vertical orientation, constant tilt and/or whether the electronicdevice 100 is stationary. The measurement of tilt relative to gravity isreferred to as “static acceleration,” while the measurement of motionand/or vibration is referred to as “dynamic acceleration.” A gyroscopecan be used in a similar fashion.

Other components 120 operable with the one or more processors 112 caninclude output components such as video outputs, audio outputs, and/ormechanical outputs. Examples of output components include audio outputssuch as speaker port 107, earpiece speaker, or other alarms and/orbuzzers and/or a mechanical output component such as vibrating ormotion-based mechanisms. Still other components will be obvious to thoseof ordinary skill in the art having the benefit of this disclosure.

It is to be understood that FIG. 1 is provided for illustrative purposesonly and for illustrating components of one electronic device 100 inaccordance with embodiments of the disclosure, and is not intended to bea complete schematic diagram of the various components required for anelectronic device. Therefore, other electronic devices in accordancewith embodiments of the disclosure may include various other componentsnot shown in FIG. 1, or may include a combination of two or morecomponents or a division of a particular component into two or moreseparate components, and still be within the scope of the presentdisclosure.

Turning now to FIG. 2, illustrated therein is the electronic device 100in a closed state. In this state, the first device housing 102 has beenpivoted about the hinge 101 toward the second device housing 103 to aclosed position 201. When in the closed position 201, a front surface202 of the first device housing 102 abuts a front surface 203 of thesecond device housing 103. Effectively, the first device housing 102 andthe second device housing 103 are analogous to clam shells that havebeen shut by the claim, thereby giving rise to the “clamshell” style ofdevice.

In some embodiments, features can be included to further retain theelectronic device 100 in the closed position 201. Illustrating byexample, in another embodiment, a mechanical latch can be included toretain the first device housing 102 and the second device housing 103 inthe closed position 201. In still another embodiment, magnets can beincorporated into the front surface 202 of the first device housing 102and the front surface 203 of the second device housing 103. Forinstance, magnets can be placed in the first device housing 102 and thesecond device housing 103 to retain the first device housing 102 and thesecond device housing 103 in the closed position 201. In still otherembodiments, frictional elements can be incorporated into the hinge 101to retain the first device housing 102 and the second device housing 103in a particular position. A stator motor could be integrated into thehinge 101 as well. Still other mechanical structures and devicessuitable for retaining the electronic device 100 in the closed position201 will be obvious to those of ordinary skill in the art having thebenefit of this disclosure.

Turning now to FIG. 3, the electronic device 100 is shown beingtransitioned from the closed position (201) of FIG. 2 to a partiallyopen position. Specifically, the first device housing 102 is pivotingabout the hinge 101 away from the second device housing 103 toward anopen position. The position shown in FIG. 3 is a “tent position” 301.

Turning now to FIGS. 4 and 5, illustrated therein is the electronicdevice 100 in an open position 401. In the open position, the firstdevice housing 102 is rotated about the hinge 101 180-degrees out ofphase with the second device housing 103 such that the first devicehousing 102 and the second device housing 103 effectively define aplane. The display 105 has been elongated into a flat position.

With particular attention to FIG. 5, one or more components of the hinge101 can be seen. In this illustrative embodiment, the hinge 101 includesa cam. A first side 502 of the cam can be seen on one side of thedisplay 105, while a second side 503 of the cam can be seen on anotherside of the display 105. Optionally, a first toothed wheel 504 and asecond toothed wheel 505 can be disposed adjacent to the first side 502of the cam 502. Where included, the toothed wheels 504,505 can engage tocreate a symmetric angular rotation of the first device housing 102 andthe second device housing 103 when the first device housing 102 pivotsabout the hinge 101 relative to the second device housing 103.

In one or more embodiments an optional third toothed wheel 506 and anoptional fourth toothed wheel 507 are situated adjacent to the secondside 503 of the cam to perform the same function. In this illustrativeembodiment, the cam is situated farther interior of the electronicdevice 100 than are the first toothed wheel 504, the second toothedwheel 505, the third toothed wheel 506, or the fourth toothed wheel 507.Said differently, in this embodiment the cam sits between the engagementof the first toothed wheel 504 and the second toothed wheel 505, and theengagement of the third toothed wheel 506 and the fourth toothed wheel507.

Turning now to FIG. 6, the electronic device 100 is shown with theflexible display (105), as well as any overlaying fascia, removed sothat additional details of the hinge 101 can more readily be seen. Asshown in FIG. 6, in one or more embodiments the hinge 101 comprises thecam 601, a first support plate 602 pivotally coupled to a first side 605of the cam and extending distally into the first device housing 102 fromthe first side 605 of the cam 601, and a second support plate 603pivotally coupled to a second side 606 of the cam 601 and extendingdistally into the second device housing 103 from the second side of thecam 601.

In one or more embodiments, the first device housing 102 and the seconddevice housing 103 each define linear recesses 608,609 into which theflexible display may be positioned. In one or more embodiments, theflexible display (105) is positioned within the linear recess 608 of thefirst device housing 102 and the linear recess 609 of the second devicehousing 103 so that it—or a fascia disposed atop the flexible display(105)—sits flush with the interior surface 610 of the first devicehousing 102 and the interior surface 611 of the second device housing103. In other embodiments, the linear recess 608,609 will be omitted,and the flexible display (105) and any accompanying fascia will simplysit atop planar surfaces defined by the interior surface 610 of thefirst device housing 102 and the interior surface 611 of the seconddevice housing 103.

Where the linear recesses 608,609 are included, the flexible display(105) can be positioned within these linear recesses 608,609 to span thehinge 101. Regardless of whether the linear recesses 608,609 areincluded, when the first device housing 102 pivots about the hinge 101relative to the second device housing 103 to the axially displaced, openposition shown in FIG. 6, the first support plate 602, the cam 601, andthe second support plate 603 bridge the linear recesses 608,609 (orplanar interior surfaces in the other embodiment) to provide positivemechanical support for the flexible display (105).

Where electrical components, e.g., processors, memories, communicationcircuits, and other component described in the schematic block diagram(111) of FIG. 1 are positioned in each of the first device housing 102and the second device housing 103, a flexible conductor (not shown) canbe included between the hinge 101 and the flexible display (105). Theflexible conductor, which can bend as the first device housing 102 andthe second device housing 103 pivot about the hinge 101 to the closedposition (201), allows electrical signals to pass back and forth betweencircuit components disposed in the first device housing 102 and thesecond device housing 103. In some embodiments, the flexible conductorcan provide additional mechanical support for the flexible display whenthe first device housing 102 and the second device housing 103 pivotabout the hinge 101 to the closed position (201) as well.

In one or more embodiments, one or more spring-loaded trays can beincluded within one or both of the first device housing 102 or thesecond device housing 103. In the illustrative embodiment of FIG. 6, atray 604, which is spring loaded and slidable, and which is disposedwithin the first device housing 102, is visible. It should be noted thatwhile the tray 604 is shown only in the first device housing 102 in thisillustrative embodiment, it could be disposed in the second devicehousing 103 as well. Additionally, in other embodiments both the firstdevice housing 102 and the second device housing 103 could include traysas well.

In one or more embodiments, a first end of the flexible display (105)can be coupled to the second device housing 103. The second end of theflexible display (105) can then be coupled to the tray 604. In one ormore embodiments, the tray 604 is slidably coupled to the first devicehousing 102, and is biased away from the hinge 101 by a spring 607. Itshould be noted that while a spring 607 is used to bias the tray 604away from the hinge 101 in this illustrative embodiment, in otherembodiments the spring 607 can be replaced by a damper device 612. Inone or more embodiments, the damper device 612 comprises a spring with anested shock damper, which can be pneumatic or hydraulic, to dampen theaction of the spring. Other devices suitable for use instead of thespring 607 will be obvious to those of ordinary skill in the art havingthe benefit of this disclosure.

Once again it should be noted in the discussion of the tray 604 andspring 607 that while only one tray 604 is shown in FIG. 6, the seconddevice housing 103 could likewise include a tray that is slidablycoupled to the second device housing 103, and is biased away from thehinge 101 by at least another spring, damper device, or other springyobject. In such an embodiment, rather than being coupled to the seconddevice housing 103, the first end of the flexible display (105) could becoupled to the second tray.

In either embodiment, the spring(s) 607 biases the tray 604 away fromthe hinge 101 to flatten the flexible display (105) when the firstdevice housing 102 pivots about the hinge 101 away from the seconddevice housing 103 to the open position (401). Where a flexibleconnector is included, it can have its first end coupled to the seconddevice housing 103, while a second end is coupled to a tray 604. In oneor more embodiments, the spring 607 biases the tray 604 away from thehinge 101, and thus away from the second device housing 103, tostraighten the flexible display (105) when the first device housing 102is pivoted about the hinge 101 away from the second device housing 103to the open position (401).

Turning now to FIG. 7, illustrated therein is another view of theelectronic device 100 is shown with the first support plate (602) andthe second support plate (603) removed so that additional details of thefirst device housing 102 and the second device housing 103 can morereadily be seen. As shown in FIG. 7, in one or more embodiments each ofthe first device housing 102 and the second device housing 103 define asupport plate receiving recess 702,703. In this illustrative embodiment,the support plate receiving recess 702 of the first device housing 102is disposed to a first side (605) of the cam 601, while the supportplate receiving recess 703 of the second device housing 103 is disposedto the second side (606) of the cam 601.

In one or more embodiments, the support plate receiving recesses 702,703provide recessed, open space within the first device housing 102 and thesecond device housing 103 that allows the flexible display (105) room toform a service loop when the first device housing 102 and the seconddevice housing 103 pivot about the hinge 101 to the closed position(201). Such a service loop will be shown below with reference to FIG. 8.This service loop occurs due to the fact that the flexible display (105)deforms when the first device housing 102 pivots about the hinge 101relative to the second device housing 103 from the axially displacedopen position (401) to the closed position (201).

In one or more embodiments, each support plate receiving recess 702,703comprises an inclined plane 704,705. In this illustrative embodiment,the first support plate receiving recess 702 defines an inclined plane704 that is disposed distally a predefined distance 706 across a bottomsurface 708 of the first support plate receiving recess 702 from the cam601. Similarly, the second support plate receiving recess 703 defines aninclined plane 705 that is disposed distally a predefined distance 707across a bottom surface 709 of the second support plate receiving recess703 from the cam 601.

In this illustrative embodiment, the first device housing 102 and thesecond device housing 103 each define linear recesses 608,609 into whichthe flexible display may be positioned. In such an embodiment, eachsupport plate receiving recess 702,703 is disposed between a respectivelinear recess 608,609 and the hinge 101. For example, in thisillustrative embodiment the support plate receiving recess 702 of thefirst device housing 102 is disposed between the linear recess 608 ofthe first device housing 102 and the hinge 101. Similarly, the supportplate receiving recess 703 of the second device housing 103 is disposedbetween the linear recess 609 of the second device housing 103 and thehinge 101.

Turning now to FIG. 8, illustrated therein is a cut away view of theelectronic device 100. In this illustration, the flexible display 105 ispositioned within the linear recesses 608,609 of the first devicehousing 102 and the second device housing 103, respectively, with afirst end of the flexible display 105 is coupled to the tray (604) inthe first device housing 102 and a second end of the flexible display105 coupled to the second device housing 103.

As shown in FIG. 8, the first device housing 102 and the second devicehousing 103 have been pivoted about the hinge 101 to the closed position(201). In one or more embodiments, when this occurs, a distal end802,803 of each of the first support plate 602 and the second supportplate 603 travels along its respective inclined plane 704,705 between afirst position (shown in FIG. 9) within the first device housing 102 andthe second device housing 103, respectively, to a second position (shownin FIG. 8) within the first device housing 102 and the second devicehousing 103, respectively.

The distal ends 802,803 of each of the first support plate 602 and thesecond support plate 603 therefore travel, in one or more embodiments,along their respective inclined planes 704,705 between the firstposition of FIG. 9 within the first device housing 102 and the seconddevice housing 103, respectively, to the second position of FIG. 8within the first device housing 102 and the second device housing 103,respectively, when the first device housing 102 and the second devicehousing 103 pivot about the hinge 10 from an axially displaced openposition (401) to the closed position (201) of FIG. 8. When this occurs,the first support plate 602, the cam 601, and the second support plate602 define boundaries within which the flexible display 105 defines aservice loop 805. The area opened for the service loop 805 by thetranslation of the first support plate 602 and the second support plate602, in one embodiment, has a radius of at least five millimeters. Sucha radius prevents the flexible display 105 from kinking or folding. Italso works to minimize mechanical memory problems when the first devicehousing 102 and the second device housing 103 pivot about the hinge 101to the open position (401).

Turning now to FIG. 9, the first device housing 102 and the seconddevice housing 103 have been rotated about the hinge 101 to the axiallydisplaced open position (401). When this occurs, due to the action ofthe cam 601, the distal ends 802,803 of the first support plate 602 andthe second support plate 603 translate up their respective inclinedplanes 704,705 from the second position of FIG. 8 to the first positionshown in FIG. 9. In the illustrative embodiment of FIG. 9, when thedistal ends 802,803 of the first support plate 602 and the secondsupport plate 603 fully translate up their respective inclined planes704,705 from the second position of FIG. 8 to the first position shownin FIG. 9, they sit atop ends 902,903 of the inclined planes 704,705.

In this position, and as shown in FIG. 9, when the distal ends 802,803of the first support plate 602 and the second support plate 603 fullytranslate up their respective inclined planes 704,705 from the secondposition of FIG. 8 to the first position shown in FIG. 9, the firstsupport plate 602, the cam 601, and the second support plate 603 bridgethe linear recess 608 of the first device housing 102 and the linearrecess 609 of the second device housing 103 when the first devicehousing 102 and the second device housing 103 are in an axiallydisplaced open position shown in FIG. 9.

By comparing FIG. 8 and FIG. 9, a number of characteristics ofembodiments of the disclosure can be seen. For example, in thisillustrative embodiment the support plates 602,603 are closer to theflexible display 105 when in the first position of FIG. 9, and cantherefore provide mechanical support for the flexible display 105 bybridging the linear recess 608 of the first device housing 102 and thelinear recess 609 of the second device housing 103 when the first devicehousing 102 and the second device housing 103 are in an axiallydisplaced open position shown in FIG. 9. By contrast, as shown in FIG.8, the support plates 602,603 and are farther from the flexible display105 when in the second position. This occurs due to the fact that thedistal ends 802,803 of the each of the first support plate 602 and thesecond support plate 603 travel along their corresponding inclined plane704,705 from the first position to the second position when the firstdevice housing 102 and the second device housing 103 pivot about thehinge 101 from the axially displaced open position to the closedposition to allow the flexible display to define a service loop 806shown in FIG. 8.

In one or more embodiments, the support plates 602,603 are farther fromexterior surfaces 904,905 of the first device housing 102 and the seconddevice housing 103 when in the first position of FIG. 9, but are closerto those exterior surfaces 904,905 of the first device housing 102 andthe second device housing 103 when in the second position of FIG. 8.This results in the second position of FIG. 8 being deeper, relative tothe interior surfaces 610,611 of the first device housing 102 and thesecond device housing 103, respectively, than the first position of FIG.9.

As shown in FIG. 9, where included, the linear support recesses 608,609of the first device housing 102 and the second device housing 103 definea support plane for the flexible display 105 on sides of the firstdevice housing 102 and the second device housing 103 exterior of thesupport plate receiving recesses 702,703 of the first device housing 102and the second device housing 103, respectively. However, the firstsupport plate 602, the cam 601, and the second support plate 603 bridgethis support plane of the first device housing 102 and the support planeof the second device housing 103 in the second position of FIG. 9 tomechanically support the flexible display 105 when the first devicehousing 102 and the second device housing 103 pivot about the hinge 101to the axially displaced open position (401) from the closed position(201). In this illustrative embodiment, the first support plate 602, thecam 601, and the second support plate 603 define a contiguous planarsurface 901 spanning the support plane defined by the linear recess 608of the first device housing 102 and the support plane defined by thelinear recess 609 of the second device housing 103 in the closedposition (201).

Recall from above magnets can be incorporated into the interior surface610 of the first device housing 102 and the interior surface 611 of thesecond device housing 103. For instance, magnets can be placed in thefirst device housing 102 and the second device housing 103 to retain thefirst device housing 102 and the second device housing 103 in the closedposition (201). It should also be noted that where a tray (604) isincluded, when the first device housing 102 and the second devicehousing 103 are in the closed position, the tray (604) slides toward thehinge 101, thereby compressing the spring (607) or damper device (612).

As shown in FIGS. 8 and 9, the cam 601 and its corresponding supportplates 602,603 serve two functions. First, they provide mechanicalsupport for the flexible display 105 when the first device housing 102has pivoted about the hinge 101 relative to the second device housing103 to an axially displaced open position of FIG. 9. However, when thefirst device housing 102 pivots about the hinge 101 relative to thesecond device housing 103 to the closed position of FIG. 8 whereinterior surfaces 610,611 of the first device housing 102 and the seconddevice housing 103 abut, the support plates 602,603 translate alongtheir respective inclined planes 704,705 within the first device housing102 and second device housing 103, respectively, to recede (from thewhere interior surfaces 610,611 of the first device housing 102 and thesecond device housing 103) into the first device housing 102 and seconddevice housing 103.

Said differently, when the first device housing 102 pivots about thehinge 101 relative to the second device housing 103 to the closedposition of FIG. 9, the support plates 602,603 move toward the exteriorsurfaces 902,903 of the first device housing 102 and the second devicehousing 103, thereby receding “outward” from the interior surfaces610,611 of the first device housing 102 and the second device housing103. This “collapse” of the first support plate 602 and the secondsupport plate 603 creates a cavity 807 in the hinge portion of theelectronic device 100 shown in FIG. 8 that allows the flexible display105 to form the service loop 806. The service loop 805 prevents theflexible display 105 from being damaged or developing memory in thefolded position when the electronic device 100 is in the closed positionof FIG. 8. Advantageously, hinges 101 configured in accordance with oneor more embodiments of the disclosure provide a solution that providesthe needed system flexibility by providing support for the flexibledisplay 105 when in the open position of FIG. 9, but allows for a largeradius service loop 805 of the flexible display 105 to occur when theelectronic device 100 is in the closed position of FIG. 8.

Turning now to FIG. 10, illustrated therein are additional componentsthat may optionally be used in a hinge 101 configured in accordance withone or more embodiments of the disclosure. As shown, in one or moreembodiments the hinge 101 includes the cam 601, a first support plate602 pivotally coupled to a first side of the cam 601, and a secondsupport plate 603 pivotally coupled to a second side of the cam 601.Adjacent to an end of the cam 601 is the first toothed wheel 504, whichis defined at the end of a housing member 1001. (The second toothedwheel (505), which engages the first toothed wheel 504 is not shown inFIG. 10 so that a better view of the first toothed wheel 504 can beseen.) Adjacent to a second end of the cam 601 are the third toothedwheel 506 and the fourth toothed wheel 507. In this illustrativeembodiment, the cam 601 is positioned between the first toothed wheel504 and second toothed wheel (505), and the third toothed wheel 506 andthe fourth toothed wheel 507, respectively. Accordingly, the cam 601 isdisposed father interior of the electronic device than the first toothedwheel 504, the second toothed wheel (505), the third toothed wheel 506,and the fourth toothed wheel 507 in this illustrative embodiment.

In this illustrative embodiment, the housing members 1001,1002,1003 eachcomprise one or more screw bosses 1004,1005,1006, so that the housingmembers 1001,1002,1003 can be coupled to the first device housing (102)and the second device housing (103), respectively. Where these separatehousings members 1001,1002,1003 are used, additional components can beincorporated into them. Illustrating by example, in one or moreembodiments a follower 1007 and spring 1008 are visible.

In one or more embodiments, a corresponding follower and spring isdisposed within each of the other housing members 1001,1002,1003.Accordingly, in one or more embodiments the hinge 101 will include fourfollowers and four springs. Each spring can bias the follower againstthe end of the cam so as to lock the electronic device using the hinge101 in either the axially displaced, open position (401) or the closedposition (201).

It should be noted that while a springs 1008,1011 are used to bias thefollowers 1007,1010 against the cam 601 in this embodiment, in otherembodiments the springs 1008,1011 can be replaced by a damper device(612) as described above with reference to FIG. 6. Where this is thecase, the damper devices (612) can include spring with a nested shockdamper, which can be pneumatic or hydraulic, to dampen the action of thespring. Other devices suitable for use instead of the springs 1008,1011will be obvious to those of ordinary skill in the art having the benefitof this disclosure.

In other embodiments, these separate housing members 1001,1002,1003 willbe omitted, with the spring(s) 1008 and follower(s) 1007 simply beingincorporated into the first device housing 102 and the second devicehousing 103. In either case, in one or more embodiments the hinge 101comprises at least a first follower 1007, biased against a first side ofthe cam 601 by a spring 1008 disposed between the removed housing member(1101 in FIG. 11) and the first follower 1007, and second follower 1010,biased against a second side of the cam 601 by a spring 1011 disposedbetween housing member 1001 and the second follower 1010.

In this illustrative embodiment, the hinge 101 includes a first pivot1009 and a second pivot, which is engaging the first toothed wheel 504in FIG. 10, but that can be seen in FIGS. 8, 9, and 11. Each of thefirst pivot 1009 and the second pivot extends through an aperture in thecam 601, and engages a corresponding aperture in each of the housingmembers 1001,1002,1003 where they are included. The removal of a fourthhousing member, which would cover the first pivot 1009, illustrates howthe first pivot 1009 passes through an aperture in the cam 601 and wouldthen, by protruding through the aperture in the cam 601, engage anaperture in the removed housing member, which would be a mirror image ofhousing member 1003. The same configuration occurs with the remaininghousing members 1001,1002,1003 in one or more embodiments.

FIG. 11 shows a cutaway view of the opposite side of the hinge 101 fromthat shown in FIG. 10. From this view, the first toothed wheel 504 andthe second toothed wheel 505 can be seen. In one or more embodimentshousing member 1001, which constitutes an extension of the first devicehousing (102), comprises at least a first toothed wheel 504. In anotherembodiment, the first device housing (102) can include an edge thatterminates at the first toothed wheel 504. In one or more embodimentshousing member 1101, which was removed in FIG. 10, and which constitutesan extension of the second device housing (103), comprises at least asecond toothed wheel 505. In another embodiment, the second devicehousing (103) can include an edge that terminates at the second toothedwheel 505.

In one or more embodiments, the first toothed wheel 504 engages thesecond toothed wheel 505 when the first device housing (102) pivotsabout the hinge 101 relative to the second device housing (103). Theengagement of the first toothed wheel 504 and the second toothed wheel505 creates a symmetric angular rotation of the first device housing(102) and the second device housing (103) when the first device housing(102) pivots about the hinge relative to the second device housing(103).

FIG. 11 also shows how the first pivot 1009 and the second pivot 1108engage housing member 1001 and housing member 1101, respectively, in oneor more embodiments. By terminating in housing members 1001,1101 andpassing through the cam (601), the cam (601) is pivotable about both thefirst pivot 1009 and the second pivot 1108.

Turning now to FIG. 12, illustrated therein is another electronic device1200 configured in accordance with one or more embodiments of thedisclosure. As with the electronic device (100) of FIG. 1, in one ormore embodiments the electronic device 1200 of FIG. 12 includes a firstdevice housing 1201 and a second device housing 1202. A hinge 1203couples the first device housing 1201 to the second device housing 1202.In one or more embodiments, the first device housing 1201 is pivotableabout the hinge 1203 relative to the second device housing 1202. In FIG.12, the first device housing 1201 and the second device housing 1202 areshown pivoted about the hinge 1203 to the closed position.

In the illustrative embodiment of FIG. 12, a flexible display 1204 iscoupled to the first device housing 1201 and the second device housing1202. In this illustrative embodiment, a first end 1205 of the flexibledisplay 1204 is coupled to the first device housing 1201. A second end1206 of the flexible display 1204 is coupled to a tray 1207, which isslidably coupled to the second device housing 1202. A spring 1208 isbiased between the second device housing 1202 and the tray 1207. In oneor more embodiments, the spring 1208 biases the tray 1207 away from thehinge 1203 by applying a loading force against the second device housing1202. Accordingly, when the first device housing 1201 is pivoted aboutthe hinge 1203 away from the second device housing 1202 to an openposition (1301) shown in FIG. 13, the spring 1208 biases the tray 1207away from both the loading point in the second device housing 1202 andthe hinge 1203, thereby stretching the flexible display 1204, whichspans the hinge 1203.

In the illustrative embodiment of FIG. 12, each of the first devicehousing 1201 and the second device housing 1202 define an inclined plane1209,1210. In one or more embodiments, a distal end 1211,1212 of thefirst support plate 1213 and the second support plate 1214 translatesalong its corresponding inclined plane 1209,1210, i.e., distal end 1211translates along inclined plane 1209 and distal end 1212 translatesalong inclined plane 1210, when the first device housing 1201 and thesecond device housing 1202 pivot about the hinge 1023 from the axiallydisplaced open position (1301) to the closed position, or vice versa.

In this illustrative embodiment, the hinge 1203 comprises a cam 1215,the first support plate 1213 and the second support plate 1214. Each ofthe first support plate 1213 and the second support plate 1214 defines afirst major face 1217 and is pivotally coupled the cam 1215. In thisembodiment, the first support plate 1213 is pivotally coupled to a firstside of the cam 1215, while the second support plate 1214 is pivotallycoupled to a second side of the cam 1215.

When the first device housing 1201 and the second device housing 1202are in an axially displaced open position (1301), shown in FIG. 13, thefirst major face 1217 of the first support plate 1213 and the secondmajor face 1218 of the second support plate 1214 abut and mechanicallysupport planar surfaces of the flexible display 1204, just as supportplates (602,603) did in FIG. 9. However, when the first device housing1201 and the second device housing 1202 pivot about the hinge 1203 fromthe axially displaced open position to the closed position shown in FIG.12, the first major face 1217 of the first support plate 1213 and thesecond major face 1218 of the second support plate 1214 tangentiallyabut a service loop 1216 defined by the flexible display 1204.

As previously described, when the first device housing 1201 and thesecond device housing 1202 are pivoting about the hinge 1203, a distalend 1211,1212 of the first support plate 1213 and the second supportplate 1214 abuts and translates along its corresponding inclined plane1209,1210. Also, as before, the first device housing 1201 and the seconddevice housing 1202 define a linear recess 1219,1220 into which theflexible display 1204 is situated. The first major face 1217 of thefirst support plate 1213 and the second major face 1218 of the secondsupport plate 1214 define planar extensions of the linear recess 1219 ofthe first device housing 1201 and the linear recess 1220 of the seconddevice housing 1202 when the first device housing 102 and the seconddevice housing 1202 are in the axially displaced open position (1301) ofFIG. 13, just as support plates (602,603) did in FIG. 9. However, asshown in FIG. 12, the first major face 1217 of the first support plate1213 and the second major face 1218 of the second support plate 1214 arediscontiguous with the linear recess 1219,1220 when the first devicehousing 1201 and the second device housing 1202 housing are in theclosed position.

Turning now to FIG. 14, illustrated therein are various embodiments ofthe disclosure. At 1401, an electronic device comprises a first devicehousing and a second device housing. At 1401, the electronic devicecomprises a hinge coupling the first device housing to the second devicehousing. At 1401, the first device housing is pivotable about the hingerelative to the second device housing.

At 1401, the hinge comprises a cam. At 1401, the hinge comprises a firstsupport plate pivotally coupled to a first side of the cam and extendingdistally into the first device housing from the first side of the cam.At 1401, the hinge comprises a second support plate pivotally coupled toa second side of the cam and extending distally into the second devicehousing from the second side of the cam.

At 1401, each of the first device housing and the second device housingdefine a support plate receiving recess comprising an inclined plane. At1401, a distal end of each of the first support plate and the secondsupport plate travels along the inclined plane between a first positionwithin the first device housing and the second device housing,respectively, to a second position within the first device housing andthe second device housing, respectively, when the first device housingand the second device housing pivot about the hinge from an axiallydisplaced open position to a closed position.

At 1402, the second position of 1401 is deeper within the first devicehousing and the second device housing, respectively, than the firstposition. At 1403, each of the first device housing and the seconddevice housing of 1402 define a linear recess. At 1403, the supportplate receiving recess is situated between the linear recess and thehinge.

At 1404, the electronic device of 1403 further comprises a flexibledisplay coupled to the first device housing and the second devicehousing and spanning the hinge. At 1405, the flexible display of 1404 ispositioned within the linear recess.
